What etresoft said... and, just as an example, I was able to download that Visual Studio Code for Mac at about 20Mbps, so there are a lot of factors in play. FWIW, I am on my home wifi and a speed test tells me I could reach 80Mbps. Yes, I have a fairly speedy internet connection.
It may also be that you have installed some software in your mac that results in a lower bandwidth. Stuff like antivirus, or network monitoring stuff like Little Snitch, or possibly other things could get in the way.
And concerning Apple watching this forum: yes, it is monitored, but not as way to get user feedback. It is mostly to ensure that users follow the rules. If you have relevant feedback to provide, you should use the feedback page:
